COOKING-STOVE.

Specification forming part of Letters Patent No. 58,638, dated October9, 1866.

To all whom it may concern.-

Be it known that I, DANIEL GRAVES, of Seneca, in the county of McHenryand State of Illinois, have invented certain new and useful Improvementsin (looking-Stoves, which I propose to call the Frustnm Oool;Stove; andI do hereby declare that the followingis afull, clear, and exactdescription thereof, reference being had to the accompanying drawing,makin g part of this specification.

The figure is a vertical central section of my invention, showing therelative arrangement of the various fines and plates. The arrowsindicate the direction of the draft and of the caloric currents.

The nature of this invention consists in such a construction andarrangement of the plates in a base-burning cylinder-stove as to providea system of griddleholes in the top plate, and also several in the broadannular hearth below and also in converting the space between the topplate and the hearth into a baking or heating oven by sections ofreflectors to inclose the said space.

To enable others skilled in the art to make and use my invention, I willdescribe its construction and operation.

The base-plate A of the stove may be made of cast-iron, and it isprovided with a small projecting hearth, J, on one side. To thisbase-plate is attached, by riveting or otherwise, a frustum-plate, B. Tothe top of this is locked an inverted frustum, O. In the top of this isplaced a firepot, D, which should be cast with three or more lugs orhangers, h, for the support of the primary ash-pan E. F is also aninverted frustum, and upon the top or upper edge of it rests the broadannular cast-iron hearth-plate G, which has a raised center, forming afrustum, and upon the top of it is attached the inverted frust-um H.This constitutes the outer cylinder or casing of the stove, and the topplate, T, rests upon the upper edge of it. This top plate may beprovided with four griddlc holes, and, if desired, with the ordinarydetachable center pieces.

The base-plate A, hearth-plate G, and the top T, also the fire-pot D andash-pan E, may

be cast. The otherplates may all be made of sheet-iron, out and formedin the usual way.

The damper or draft-plate d is designed to close the flue through whichair is admitted to supply and efiect the combustion, and also throughwhich the ashes may be removed.

The circle of the hearth Gr may be divided by two, three, or more radialplates, extending from the hearth to the top and from the bodyof thestove outward, as indicated by the dotted line N, and each or either ofthe sections thus formed maybe inclosed by an oven or refiector-case,It, whichjthus provides a complete baking-oven of more than ordinarycapacity for such a sized stove.

I would recommend a seven-inch pipe, P, for a stove enlarged about fourtimes from the drawing.

It will be seen that this stove affords a large amount of heating orradiating surface, and

besides being very compact, it affords a remarkably large amount ofcooking capacity, as there are four griddles exposed on the top at alltimes, and when the oven is not in use three or four more in the hearthare rendered available.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination and relative arrange ment of the frustuin plates B,G, F, and H, substantially as herein shown and described, in theformation of cooking-stoves, for the purposes set forth.

2. The broad annular hearth G, when arranged to be heated by thecaloric-current passing under it, substantially as and for thelpurposesshown and described.

3. The double frustuni B O, which constitutes the inner draft-tlue andgives a radiating direction to the caloric-current, as shown.

at. The segmental reflector-plates jior cases It, in combination withthe frustum-stove, constituting an annular heating or baking oven, asshown and described.
